Description
i 143836 oin 143836 o
Den foreliggende opfindelse angår et tobaksprodukt, sædvanligvis cylinderformet, med tobaksfyld og omhyl-ning for tobaksfyldet, og opfindelsen angår tillige en om-hylning til anvendelse ved fremstilling af tobaksproduktet.The present invention relates to a tobacco product, usually cylindrical, with a tobacco filling and a tobacco filling envelope, and the invention also relates to a wrapper for use in the manufacture of the tobacco product.
5 Det har været praksis i en årrække at anvende for skellige filteranordninger i cigaretter og andre tobaksprodukter til reducering af mængden af visse bestanddele i røgen. Selv om nogle af disse anordninger har været anvendt med relativt godt resultat, lader de stadig meget tilbage 10 at ønske med hensyn til den måde, hvorpå de reducerer mange af de materialer, der findes i cigaretrøg. Cigaretpapirer modificeres konventionelt ved tilsætning af forskellige kemikalier til forbedring af cigarettens brændhastighed og askekarakteristika som beskrevet i USA-patentskrifterne nr.5 It has been the practice for a number of years to use various filter devices in cigarettes and other tobacco products to reduce the amount of certain components in the smoke. Although some of these devices have been used with relatively good results, they still leave a lot to be desired in terms of how they reduce many of the materials found in cigarette smoke. Cigarette papers are conventionally modified by the addition of various chemicals to improve the burning rate and ash characteristics of the cigarette as disclosed in U.S. Pat.
15 2.580.611, 2.652.834 og 2.733.720, men sådanne papirer har ringe, om overhovedet nogen, virkning på cigaretrøgen. Det er ligeledes velkendt at anvende et calciumcarbonat-fyld-stof ved fremstilling af cigaretpapir til forbedring af papirets udseende og egenskaber, som beskrevet i de oven-20 nævnte patentskrifter. Sådanne konventionelle cigaretpapirer har imidlertid ingen signifikant virkning på reduktionen af uønskede bestanddele i cigaretrøgen.15 2,580,611, 2,652,834 and 2,733,720, but such papers have little, if any, effect on the cigarette smoke. It is also well known to use a calcium carbonate filler in the manufacture of cigarette paper to improve the appearance and properties of the paper, as described in the above-mentioned patents. However, such conventional cigarette papers have no significant effect on the reduction of unwanted constituents in the cigarette smoke.
USA-patentskrift nr. 3.395.714 beskriver en sammensat omhylning til cigaretter, hvor den ydre omhylning er 25 konventionelt cigaretpapir, og den indre omhylning nærmest tobakssøjlen er et plastarjcmateriale, der er varmeisolerende og smelter ved lav temperatur. Det er angivet, at en sådan kombination nedsætter temperaturen af cigarettens brændezone, hvilket resulterer i en forlængelse af cigarettens lavtempe-30 ratur-destillationszone og en stigning i røgens nicotin- og smagsstoflndhold.U.S. Patent No. 3,395,714 discloses a composite casing for cigarettes, the outer casing being 25 conventional cigarette paper, and the inner casing closest to the tobacco column being a plastic insulating material which is heat insulating and melts at low temperature. It is stated that such a combination lowers the temperature of the cigarette burn zone, resulting in an extension of the cigarette's low temperature distillation zone and an increase in the nicotine and flavor content of the smoke.
I den kendte teknik er der også beskrevet forskellige metalovertrukne cigaretpapirer. USA-patentskrift nr.Various prior art metal coated cigarette papers are also disclosed in the prior art. U.S. Pat.
3.586.005 foreslår f.eks. en cigaretpapiromhylning, hvor 35 papiret er overtrukket på enten den ene eller begge overflader med et tyndt lag af et metal, såsom aluminium, eller legeringer på aluminiumbasis. Det hævdes i dette patentskrift,3,586,005 suggests e.g. a cigarette paper envelope wherein the paper is coated on either one or both surfaces with a thin layer of a metal such as aluminum or aluminum-based alloys. It is claimed in this patent,
OISLAND
143834 2 at cigaretter fremstillet med sådanne omhylninger har en højere spidsbrændetemperatur, og at omhylningerne danner et relativt kontinuerligt og ubrudt hylster eller rør for den brændte og brændende tobak. Det er angivet, at dette 5 rør beskytter mod luft, der kommer radialt ind i den brændende zone, og virker som en ledning i længderetningen for luften, således at mere luft passerer gennem den brændende zone igennem hele dennes tværsnit, hvorved der bliver mere oxygen tilgængeligt til en mere fuldstændig forbrænding og 10 højere brændetemperaturer. Anvendelsen af sådant metalover-trukket papir som omhylning for cigaretter er upraktisk, fordi den lange aske, der frembringes, har tilbøjelighed til at trække den brændende kegle ud af cigaretten, når asken slås af under rygningen.That cigarettes made with such envelopes have a higher peak burning temperature and that the envelopes form a relatively continuous and unbroken casing or tube for the burnt and burning tobacco. It is stated that this tube protects against air entering radially into the burning zone and acts as a longitudinal conduit for the air, so that more air passes through the burning zone through its entire cross section, thereby providing more oxygen available for a more complete combustion and 10 higher burning temperatures. The use of such metal-coated paper as wrapping for cigarettes is impractical because the long ash produced tends to pull the burning cone out of the cigarette when the ash is turned off during smoking.
15 Det er et formål med den foreliggende opfindelse at tilvejebringe et tobaksprodukt med en reduceret sidestrømsrøg og en reduceret mængde gasformige og partikel-formige bestanddele i hovedstrømsrøgen.It is an object of the present invention to provide a tobacco product having a reduced sidestream smoke and a reduced amount of gaseous and particulate components in the main stream smoke.
Den foreliggende opfindelse angår således et to-20 baksprodukt, sædvanligvis cylinderformet, med tobaksfyld og omhylning for tobaksfyldet, hvilket tobaksprodukt er ejendommeligt ved, at omhylningen omfatter et brændbart, porøst papirark af cellulosefibre og finpulveriserede carbonpar-tikler som en indre omhylning, hvilke carbonpartikler udgør 25 mindst 5 vægtprocent af arket, og konventionelt cigaretpapir eller cigardæksblad med gqd brændbarhed som ydre omhylning, som omgiver og er i kontakt med den indre omhylning.The present invention thus relates to a two-baked product, usually cylindrical, with tobacco-filled and tobacco-filled casing, characterized in that the casing comprises a combustible porous sheet of cellulose fibers and finely powdered carbon particles as an inner casing which constitutes carbon particles. 25 at least 5% by weight of the sheet, and conventional cigarette paper or cigar cover sheet with gqd flammability as outer casing, which surrounds and is in contact with the inner casing.
Opfindelsen angår desuden en omhylning til an-30 vendelse ved fremstilling af et tobaksprodukt, hvilken omhylning er ejendommelig ved, at den er sammensat af et brændbart, porøst papirark af cellulosefibre og finpulveriserede carbonpartikler som indre omhylning, hvilke carbonpartikler udgør mindst 5 vægtprocent af arket, og i kontakt med dette 35 et ark af konventionelt cigaretpapir eller cigardæksblad med god brændbarhed som ydre omhylning.The invention further relates to a sheath for use in the manufacture of a tobacco product, the sheath being characterized in that it is composed of a combustible, porous sheet of cellulose fibers and fine powdered carbon particles as inner sheath which comprises at least 5% by weight of the sheet. and in contact therewith a sheet of conventional cigarette paper or cigar cover sheet with good flammability as outer casing.

Det carbonholdige papir til omhylningen ifølge den foreliggende opfindelse kan fremstilles under anvendelse af et gængs materiale til papirfremstilling, såsom træpulp eller hørfibre, hvortil der er sat en til-5 strækkelig mængde pulveriseret carbon-fyIdstof. Materialet er fiberpulp og carbon-fyIdstof anvendes derpå til fremstilling af et papirark på konventionelle papirfremstillingsmaskiner. Det specifikke fibermateriale, hvoraf den carbonholdige omhylning fremstilles, er ikke kritisk, og en hvil-10 ken som helst af de cellulosefiberpulps, der anvendes ved papirfremstilling, kan anvendes. De fiberpulps, der almindeligvis anvendes til fremstilling af papiromhylninger til cigaretter, eller de tobaksmaterialer, der anvendes til fremstilling af cigardæksblade, foretrækkes. Foruden træ- og 15 hørfibre kan materialet således være pulpformige tobaksstængler eller -stilke, hvortil carbon-fyldstoffet er sat, eller carbonet kan sættes til det materiale, der anvendes til fremstilling af rekonstituerede tobaksark til cigardæksblade.The carbonaceous paper for the envelope of the present invention can be made using a conventional paper making material, such as wood pulp or flax fiber, to which a sufficient amount of powdered carbon fiber is added. The material is fiber pulp and carbon fiber is then used to make a sheet of paper on conventional papermaking machines. The specific fiber material from which the carbonaceous envelope is made is not critical, and any of the cellulose fiber pulps used in papermaking can be used. The fiber pulps commonly used to make paper wrappers for cigarettes, or the tobacco materials used to make cigar cover sheets, are preferred. Thus, in addition to wood and flax fibers, the material may be pulp-shaped tobacco stalks or stems to which the carbon filler is added, or the carbon may be added to the material used to make reconstituted tobacco sheets for cigar cover leaves.
Det carbonholdige papir anvendes ideelt som en 20 indre omhylning under en normal ydre omhylning for tobakssøjlen i cigaretten eller cigaren. Konventionelt cigaretpapir eller cigardæksblade anvendes som den ydre omhylning for tobaksproduktet. En sådan kombination reducerer den mængde tobak, der er nødvendig til fremstilling af et tilfredsstil-25 lende produkt, forøger fastheden af tobakssøjlen og ændrer ikke cigarettens eller cigarens udseende, eftersom den ydre omhylning af konventionelt cigaretpapir eller cigardæksblade skjuler den grå, carbonholdige, indre foring.The carbonaceous paper is ideally used as an inner cover under a normal outer cover for the cigarette or cigar tobacco column. Conventional cigarette paper or cigar cover sheets are used as the outer cover of the tobacco product. Such a combination reduces the amount of tobacco needed to produce a satisfactory product, increases the strength of the tobacco column and does not alter the appearance of the cigarette or cigar since the outer casing of conventional cigarette paper or cigar cover leaves conceals the gray, carbonaceous inner lining. .
Ved cigaretter er konstruktionen således, at 30 den indre omhylning af carbonholdigt papir kan være lukket eller åben. Hvis den er åben, holder den lukkede ydre omhylning den indre omhylning rundt om cigarettens omkreds.In cigarettes, the construction is such that the inner casing of carbonaceous paper may be closed or open. If open, the closed outer casing holds the inner casing around the perimeter of the cigarette.
Omhylningens carbonindhold kan variere inden for et stort område afhængigt af den ønskede reduktion i parti-35 kelformige og gasformige bestanddele. Carbonmængder på mindst 4 1Λ 3 8 3 Λ Ο 5 vægtprocent baseret på papirets vægt giver tilfredsstillende resultater, og mængder så høje som 90% kan anvendes med godt resultat. Høje mængder carbon-fyIdstof har tilbøjelighed til at frembringe store reduktioner i partikel-5 formige og gasformige bestanddele. I den carbonholdige om-hylning kan der anvendes enten aktiveret carbon eller uak-tiveret carbon, selv om aktiveret carbon foretrækkes. Carbo-ner lige fra pulveriseret kul til kokosnøddeskal-trækul med særdeles høj aktivitet er blevet anvendt med godt resultat.The carbon content of the envelope may vary within a wide range depending on the desired reduction in particulate and gaseous constituents. Carbon amounts of at least 4 1Λ 3 8 3 Λ Ο 5% by weight based on the weight of the paper give satisfactory results and quantities as high as 90% can be used with good results. High amounts of carbon fuel tend to produce large reductions in particulate and gaseous constituents. In the carbonaceous envelope, either activated carbon or inactivated carbon can be used, although activated carbon is preferred. Carbons ranging from pulverized coal to coconut shell charcoal with extremely high activity have been used successfully.
10 Andre typiske eksempler er aktiverede trækul, aktiverede formalingsspildcarboner, aktivt kul og jordoliebaserede carboner, uaktiverede fede kul og pulveriserede trækulbriketter .Other typical examples are activated charcoal, activated milling waste carbons, activated charcoal and petroleum-based carbon, unactivated fatty coal and powdered charcoal briquettes.
Fra et udseendemæssigt synspunkt bør carbonets 15 partikelstørrelse være tilstrækkelig lille til, at der ikke kan ses synlige klumper i papiret. Dette er almindeligvis mere væsentligt, når det carbonholdige ark anvendes som en indre omhylning i cigaretter, eftersom større carbonpartik-ler frembringer synlige klumper under den ydre omhylning af 20 cigaretpapir. Ved cigarer er sådanne klumper mindre iøjnefaldende og derfor mere acceptable. Carbonet er fortrinsvis finpulveriseret, og det har vist sig, at partikelfor-migt carbon, der kan passere gennem en sigte med en maskevidde på 0,177 mm eller mindre, har en fordelagtig størrelse.From an appearance point of view, the particle size of the carbon should be sufficiently small that no visible lumps can be seen in the paper. This is generally more significant when the carbonaceous sheet is used as an inner casing in cigarettes, since larger carbon particles produce visible lumps under the outer casing of cigarette paper. In cigars, such lumps are less conspicuous and therefore more acceptable. The carbon is preferably finely powdered and it has been found that particulate carbon which can pass through a sieve with a mesh width of 0.177 mm or less has an advantageous size.
25 Den carbonholdige omhylning frembringer den øn skede virkning uden tilsætning af nogen af de almindeligt anvendte forbrændingsregulerende kemikalier til cigaretpapir eller cigardæksblade. Anvendelsen af forbrændingsregulerende kemikalier viser sig almindeligvis at virke syner-30 gistisk med carbonet til tilvejebringelse af forbedrede resultater med hensyn til reduktion af gasformige bestanddele og den totale mængde partikelformigt materiale i røgen foruden tilvejebringelse af bedre regulering af brændehastigheden. Det har vist sig, at de mest effektive forbræn-35 dingsregulerende kemikalier er alkalimetalhydroxider, -bicar-bonater og -carbonater, selv om mange andre alment kendte 143834 5The carbonaceous casing produces the desired effect without adding any of the commonly used combustion regulating chemicals to cigarette paper or cigar cover sheets. The use of combustion regulating chemicals is generally found to act synergistically with the carbon to provide improved results in reducing gaseous constituents and the total amount of particulate matter in the smoke in addition to providing better control of the burning rate. It has been found that the most effective combustion regulating chemicals are alkali metal hydroxides, bicarbonates and carbonates, although many other widely known
OISLAND
forbrændingsregulerende kemikalier, såsom citrat-, phosphat-og nitratsalte, kan anvendes. Det er også muligt at anvende brandretarderende midler i kombination med carbon-fyldstof-fet til modificering af omhylningens forbrændingsegenskaber.combustion regulating chemicals such as citrate, phosphate and nitrate salts can be used. It is also possible to use fire retardants in combination with the carbon filler grease to modify the combustion properties of the casing.
5 Som beskrevet ovenfor tilvejebringer carbon i om- hylningen de fleste af de gunstige virkninger i de omhandlede tobaksprodukter. Anvendelsen af et jordalkalimetalcar-bonat, såsom calcium- eller magnesiumcarbonat, som endnu et fyldstof i omhylningsmaterialet forbedrer imidlertid yder-10 ligere de virkninger, der opnås, i forhold til anvendelsen af carbon som eneste fyldstof. Den dannede totale mængde partikelformigt materiale og den dannede mængde af de vigtigste organiske bestanddele i dampfasen reduceres væsentligt ved tilsætningen af calciumcarbonat til det carbonhol-15 dige papir, endog når der tilsættes så lidt som 5% calciumcarbonat beregnet på papirets vægt. Det viser sig, at der opnås maksimale reduktioner med en total fyldstofmængde på fra ca. 50 til 80 vægtprocent i omhylningen under anvendelse af carbon som eneste fyldstof eller en carbon/calciumcarbo-20 natfyldstofblanding indeholdende mindst 5% calciumcarbonat beregnet på vægten af det færdige papir. Carbon/calcium-carbonat-forholdene kan varieres efter ønske, hvorved man kan påvirke dannelsen af den totale mængde partikelformigt materiale og de vigtigste organiske bestanddele i dampfasen 25 i hovedstrømsrøgen eller kan påvirke synlighedsgraden af sidestrømsrøgen.As described above, carbon in the casing provides most of the beneficial effects of the tobacco products in question. However, the use of an alkaline earth metal carbonate, such as calcium or magnesium carbonate, as yet another filler in the casing material further enhances the effects obtained relative to the use of carbon as the sole filler. The total amount of particulate matter formed and the amount of the major organic constituents formed in the vapor phase are substantially reduced by the addition of calcium carbonate to the carbonaceous paper, even when as little as 5% calcium carbonate is calculated based on the weight of the paper. It turns out that maximum reductions are obtained with a total filler amount of approx. 50 to 80% by weight in the casing using carbon as the sole filler or a carbon / calcium carbonate filler mixture containing at least 5% calcium carbonate based on the weight of the finished paper. The carbon / calcium carbonate ratios can be varied as desired, thereby affecting the formation of the total amount of particulate matter and the major organic constituents of the vapor phase 25 of the main stream smoke or can affect the degree of visibility of the sidestream smoke.
Det carbonholdige papirs porøsitet kan udformes således, at det svarer til de krav, der stilles til den færdige cigaret eller cigar, såsom den ønskede luftfortynding 30 af røgen. Når det carbonholdige papir anvendes som en indre omhylning, kan porøsiteten variere inden for et bredt område, eftersom porøsiteten af den totale omhylning i den færdige cigaret eller cigar kan reguleres med den ydre omhylning .The porosity of the carbonaceous paper can be designed to meet the requirements of the finished cigarette or cigar, such as the desired air dilution of the smoke. When the carbonaceous paper is used as an inner casing, the porosity can vary within a wide range, since the porosity of the total casing in the finished cigarette or cigar can be controlled with the outer casing.
35 I tobaksproduktet ifølge opfindelsen er det ligele des muligt at indføre smagsstoffer, eftersom de let sættes til det carbonholdige papir. Carbonet holder på smagsstoffet,35 In the tobacco product of the invention, it is likewise possible to incorporate flavors since they are easily added to the carbonaceous paper. The carbon holds on to the flavor,
OISLAND
143834 6 indtil det frigøres af varmen i den brændende zone således, at det går ind i sidestrøms- eller hovedstrømsrøgen. Menthol, vanillin og glycyrrhiza er eksempler på gængse smagsstoffer til cigaretter og cigarer, der er blevet sat til det carbon-5 holdige papir og anvendt med særdeles tilfredsstillende resultater.Until it is released by the heat in the burning zone so that it enters the lateral or main stream smoke. Menthol, vanillin and glycyrrhiza are examples of common flavors for cigarettes and cigars that have been added to the carbon-containing paper and used with very satisfactory results.
I cigaretrøg fra cigaretter ifølge opfindelsen opnås mere end 50% reduktion i den dannede totale mængde par-tikelformigt materiale og den dannede mængde af de vigtigste 10 organiske bestanddele i dampfasen. Lignende drastiske virkninger opnås i reduktionen af den synlige sidestrømsrøg. Medens det ikke vides med sikkerhed, hvorfor der forekommer sådanne reduktioner, er det blevet fastslået, at den carbon-holdige omhylning normalt forøger tobaksproduktets brænde-15 temperatur. Det menes, at denne stigning i brændetemperatur, især på cigarettens eller cigarens overflade, har betydning for reduktionen i de dannede mængder i røgen fra cigaretter eller cigarer, der anvender carbonholdige papir-omhylninger; også carbonet i omhylningen i medstrøm fra den brændende 20 zone er i stand til at adsorbere visse bestanddele i røgen.In cigarette smoke from cigarettes according to the invention, more than 50% reduction in the total amount of particulate matter formed and the amount of the most important 10 organic constituents in the vapor phase is obtained. Similar drastic effects are achieved in the reduction of visible sidestream smoke. While it is not known for certain why such reductions occur, it has been established that the carbonaceous casing usually increases the burning temperature of the tobacco product. It is believed that this increase in burning temperature, especially on the surface of the cigarette or cigar, has a bearing on the reduction in the amounts produced in the smoke from cigarettes or cigars using carbonaceous paper envelopes; also the carbon in the casing in co-flow from the burning zone is capable of adsorbing certain components of the smoke.
Opfindelsen illusteres i de efterfølgende eksempler.The invention is illustrated in the following examples.

Den indre omhylning af carbonholdigt papir fremstilles konventionelt ud 30 fra hørfiberpulp under anvendelse af et aktiveret træpulp-carbonfyIdstof. Carbonets partikelstørrelse er således, at det hele kan passere gennem en sigte med en maskevidde på 0,177 mm og ca. 25 til 50% kan passere gennem sigte med en maskevidde på 0,044 mm.

Der fremstilles en række carbonholdige papirer med forskellige aktiviteter, typer og mængder af carbonfyIdstof, både med og uden yderligere calciumcarbonatfyIdstof. Nogle af papirerne behandles også yderligere med oxidationskata- 15 lysatorer. Partikelstørrelsen af hvert af de afprøvede car- boner er således, at de kan passere gennem en sigte med en maskevidde på 0,177 mm eller mindre. De carbonholdige papirer fremstilles ved konventionel papirfremstillingsteknik under anvendelse af hørpulp som grundfiber, og vægten af hvert af 2 20 de færdige ark er ca. 60 g/m . Hvert af de carbonholdige ark anvendes derpå til fremstilling af en cigaret, der er 70 mm lang og ca. 8 mm i diameter, med det carbonholdige ark som indre omhylning for tobakssøjlen under en ydre omhylning af konventionelt cigaretpapir. Identiske kontrolcigaretter 25 fremstilles ud fra samme tobak og under anvendelse af den samme cigaretpapir-omhylning, men uden nogen indre omhylning af carbonholdigt papir.

Alle resultaterne er baseret på den røg, der er opnået fra brænding af 60 mm af hver cigaret med ca.A variety of carbonaceous papers are produced with various activities, types and amounts of carbonic acid, both with and without additional calcium carbonate liquid. Some of the papers are also further treated with oxidation catalysts. The particle size of each of the tested carbons is such that they can pass through a sieve with a mesh width of 0.177 mm or less. The carbonaceous papers are made by conventional papermaking technique using flax pulp as the base fiber, and the weight of each of the 20 sheets is approx. 60 g / m. Each of the carbonaceous sheets is then used to produce a 70 mm long cigarette and approx. 8 mm in diameter, with the carbonaceous sheet as the inner cover of the tobacco column under an outer cover of conventional cigarette paper. Identical control cigarettes 25 are made from the same tobacco and using the same cigarette wrapper, but without any inner wrapping of carbonaceous paper. In the tables below, the results are given as a percentage of the measured property compared to the control cigarettes without inner wrapping of carbon-containing paper. All results are based on the smoke obtained from burning 60 mm of each cigarette with approx.
